The working principle of a MOSFET is very simple. MOSFETs are basically a type of transistor, which is composed of three parts: the source, the gate, and the drain. The source is the input of the device and the gate is the control of the device. When a signal is applied to the gate electrode of the device, it causes a voltage variation which in turn causes a change in the resistance between the source and the drain. This change in resistance is what causes current to flow between the source and drain. This current is responsible for powering circuits connected to the device.

The VRF148A is a high-performance, high-frequency MOSFET, which is ideal for a variety of applications. Its single-ended gate drive provides low propagation delay, high input impedance, and low on-resistance.
